Overview

Modern cooling systems operate under heat, pressure and constant circulation, which makes them vulnerable to corrosion (especially in mixed-metal systems), foaming, and deposit build-up that can reduce heat transfer. Fleetline Antifreeze 50% is designed as a convenient, ready-to-use coolant that provides dependable low-temperature protection while helping keep cooling passages cleaner and protecting common metals used in radiators, engine blocks and cooling components.

How to use

General method (pre-mixed coolant)

1. Only open the cooling system when the engine is cool.

2. If changing coolant type/colour, drain and flush as required by the service procedure.

3. Fill with Fleetline Antifreeze 50% (use directly unless your OEM specifies otherwise).

4. Bleed air from the system and confirm the final level after warm-up.

Always follow the equipment manufacturer’s coolant specification and change intervals—especially when selecting between colour variants.
